Read sixty odd letters out to rewrite (4)
I believe the answer is:
edit
'to rewrite' is the definition.
(I've seen this before)
'read sixty odd' is the wordplay.
'odd' indicates alternate letters.
'read'+'sixty'='readsixty'
The alternating letters of 'readsixty' are 'EDIT'.
'letters out' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for edit that I've seen before include "Amend and correct" , "Revise for publication" , "Supervise the publication of" , "Rework (text)" , "work on newspaper?" .)
